Answer:

12

Step-by-step explanation:

You can solve this problem by setting up an equation.

7 more that double a number is just 2x + 7
Five less than triple that number is just 3x - 5

Since they are equal to each other, you can set them equally to each other.

2x + 7 = 3x - 5

Solve.

7 + 5 = 3x - 2x

x = 12
